Improvement in chimneys



A UNITED "STATES A SAMUEL M. Meconn, oF SPRINGFIELD, oHIo.

IMPROVEMENT IN CHZMNEVS.

Specification forming part of Letters Patent No. 117,555, dated August`1, 1871.

To all u-hom it may concern:

Be it known that I, SAMUEL M. MUGORD, of the city of Springfield, in theSta-te of Ohio, have invented a new and useful Improvement in Fire-ProofChinmey-Flues; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the saine, reference being had to theaccompanying drawing forming part of this specification.

This invention relates to improvements in reprooil chimney-dues; and itconsists in the application of earthen piping to the interior of saidfines, placed one upon the other the entire length ofthe iiues,supported from the base of the lower section, and in such manner as toleave ventilating-Spaces between the outer wall B and the inner Side ofthe chimney A, all of which will be more fully described in theSpecication.

In the drawing, Figure 1 represents a vertical Section of a chimney-nuewith the piping in po- Sition. Fig. 2 is a horizontal section on lineFig. 3 represents a section of the piping.

In the drawing, A represents a chimney-due of the ordinary construction,in the interior of' which are arranged the sections of piping B placedone upon the other to the upper end of the ue. They may be of anydesirable size and thickness to Suit the different sizes ofchimneyflues, and may be of any shape preferred.

The object of my invention is to prevent possibility of iire from thecracking ofthe brick walls of the chimneys of buildings, whereby suchgreat danger arises from lire. The cracks are often also produced by thecontraction and eX- pansion of the briclework, as well as from thesettling of the building. By my invention this difficulty iS entirelyobviated, as the piping, being loosely placed in the iiues, is notai'ected by the settling or cracking of the chimney. The air-spaces G,in the corners of the iiue tend to keep the piping cool and add to thechaught of the chimney, and serve as ventilators to rooms by apertures aa, with` or Without registers. These apertures may be made at any pointin a room, either in the fire-place or the walls of the room.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is Y The combination of the piping B with achimney-iiue A, ventilator C, and air-ducts a ct, in the manner and forthe purpose herein Set forth.
